[The correlation of results of breath analysers and laboratory blood examinations of blood-ethanol concentration (Czech and Slovak study)]. / Mezirepubliková Cesko-Slovenská studie korelace výsledku dechových analyzátoru a výsledku laboratorní analýzy pri zjistování hladiny alkoholu v krvi.

The target of this study was to compare the results of breath analysers and "lege artis" laboratory blood examinations when determining alcohol levels. This was then used to determine whether any differences exist between the two methods, and how large these differences are. 610 cases from 11 workplaces in the Czech Republic and Slovakia were analysed. The type of breath analyser was not taken into consideration. All cases had to be in the elimination phase. Difference of time between breath test and blood test were rectified through the use of reverse recomputation. It was detected that only 20.8% of the results of respiratory analyser tests correspond to the detected real alcohol level in blood. The maximum difference when a respiratory analyser measured more than a blood test was 1.34 g x kg(-1). and the maximum difference when the analyse measured less was 1.86 g x kg(-1).

[Overview of the changes in alcohol content of beers produced in the Czech Republic]. / Prehled aktuálních zmen v obsahu alkoholu u piv vyrábených v Ceské republice.

Paper concerns the alcohol contents of beer now produced. The previous and contemporary ways of beer signing as well as a complete list of beer sorts produced in the Czech Republic is presented.

[Air embolism]. / Vzduchová embolie.

Air embolism is a dramatic event which threatens the patient's life during invasive therapeutic and diagnostic procedures. Immediately after establishment of the diagnosis treatment in a hyperbaric chamber should be started. The prognosis depends to a certain extent on how quickly the patient is transferred into a hyperbaric chamber. Treatment with hyperbaric oxygen is based on fundamental physical and physiological principles of the action of compressed air and the supply of a large amount of oxygen in a dissolved form into the ischaemic tissue beyond the obstruction. Installation of hyperbaric chambers in hospitals would make successful and prompt treatment of all cases of embolism possible, as well as of some other diseases indicated for hyperbaric oxygen therapy.

[Estimation of the height of free fall of a human body on the basis of experimental expression of the degree of injury]. / Odhad výsky volného pádu lidského tela na základe pokusného vyjádrení kvantity poranení.

The author evaluated 204 deaths caused by blunt force as a result of incidence after a free fall from an altitude of 2 do 45 metres. Experimentally a score of severity od different types of traumatic changes was created. In every case the quantity of injury was expressed. Its dependence on the incident kinetic energy of the body, the mobility of incidence and rate of incidence was investigated. The closest correlation with the quantity of injury, based on mathematical and statistical evaluation, was found for the incident mobility of the body (Ns), the least one for the rate of incidence (m/s). In free falls with an incidence on a flat surface (asphalt, concrete, pavement, trampled soil the author suggests a procedure of estimation of the probability interval (p = 95%) of the altitude of the fall. The procedure could be used in forensic practice in cases with an unknown altitude of the fall and to test the trustworthiness of data concerning the altitude of the fall.

[Quantitative evaluation of accidents as a measure of the action of mechanical force]. / Pokus o kvantitativní hodnocení úrazu jako merítka úcinku mechanického násilí.

Based on 175 published cases where pedestrians were knocked down by a motor vehicle the author tested the quantitative evaluation of the injury by assessing changes of hard and soft tissues. Mathematical and statistical evaluation proved a relationship between the changes caused by the accident and the intensity of mechanical force.

[Lactic acid content and total saccharides in postmortem tissues and expressing the degree of probability in interpreting the findings]. / Obsah kyseliny mlécné a sumy sacharidu ve tkáních post mortem a vyjádrení míry pravdepodobnosti prí interpretaci nálezu.

In representative victims of aircraft accidents whose death had occurred under known conditions, a mathematically statistical evaluations of the results of biochemical examinations of the brain, heart, liver and muscular tissue has been performed. The importance of the determination of the lactic acid contents and of those of the sum of the saccharides for the purpose of an anterograde evaluation of the premortal state of the organism, has been demonstrated, and the boundary line levels of the values enabling the expression of probability in the conclusion of an expertise, have been calculated. This method of biochemical examination may be used even in common forensic medical practice, especially for the purpose of examination of cases of violent death.
